## At a glance

- Operator: Cốc Cốc
- Type: Search Engine
- RSL category: `search`

## How Centinel checks it

- **User agent**: The request calls itself this crawler. Anyone can send the same string.
- **Reverse DNS**: The client address resolves to a hostname the operator controls, and that hostname resolves back to the same address.

A request that passes one of these checks is coccocbot-image itself. One that only matches the user agent is reported as unverified. The match tokens, verification domains, and address feeds are not published here.

## Allowing or blocking it

The [crawler object](https://docs.centinelanalytica.com/api/crawlers.md) in the `/validate` response sets `access_allowed` to `true` only for a verified source that your tenant allowlists. A [policy rule](https://docs.centinelanalytica.com/admin/policy.md) can allow or block this crawler by its category, `Search Engine`.
